function Publish (
    pOperationContext : UccOperationContext


  • pOperationContext
    A value of the IUccOperationContext* (UccOperationContext, for a .NET application) type. The default value is NULL. This can be used to specify application-defined context for this publication request.


Subscribers begin to receive the category instances or the updates after this method is called. An application can verify the status of completion of this request by catching the OnPublish event as defined in _IUccPublicationEvent. The publication object can not be used for further publication operations. The OnPublish event handler is a good place to destroy the used publication object.

Win32 COM/C++ Syntax

   IUccOperationContext* pOperationContext


In a Win32 application, the return value of a method or property is always an HRESULT value indicating the status of the call to the interface member. Any result of the operation is returned as a parameter marked with the [out, retval] attribute. In contrast, in a .NET application the HRESULT value indicating an error condition is returned as a COM exception and the [out, retval] parameter becomes the return value. For the UCC API-defined HRESULT values, see Trace and Handle Errors in Unified Communications Client API .


The following example takes a category instance as a method argument, creates a publication object, advises for publication events, adds the passed category instance to the publication, and publishes the publication.

private void PublishCategoryInstance(IUccCategoryInstance cat)
   IUccPublication pub = pubMgr.CreatePublication() as IUccPublication;
   if (pub != null)
      UCC_Advise<_IUccPublicationEvent>(pub, this);
